Question

SFTP的功能在本地运行，并且配置正确。问题出在Lambda的日志中，它抱怨配置，我相信这是给我一个错误：等待握手时超时。

const config = {
    host: 'ftp.xxxx.at',
    port: '22',
    username: 'SFTP_xxx',
    password: 'xxx9fBcS45',
    MD5_Fingerprint: 'xxx:8f:5b:1a',
    protocol: "sftp",
    algorithms: {
        serverHostKey: ['ssh-rsa', 'ssh-dss']
      }
};


// get file
// get sftp file
// here ....
const get = () => {
    sftp.connect(config).then(() => {
        return sftp.get('./EMRFID_201811210903.csv', null, 'utf8', null);
    }).then((stream) => {
        let body = stream.on('data', (chunk) => {
            body += chunk;
        })
        stream.on('end', () => {

            uploadRFIDsToS3(body)
            // close connection
            sftp.end()
        });
    }).catch((err) => {
        console.log('catch err:', err)
    })
};

我在AWS中添加了VPC和安全组，但仍然出现相同的错误。我没办法解决它。

增加lambda函数的超时值。分配更多内存和超时的选项是aws中任何lambda函数的一些设置
